Integrated Monitoring of CHP Transformer Bays: Rapidox, Vibration and Ultrasound
A CHP transformer bay is transformer, breakers, cooling and switchgear in one reliability loop. How to unify Rapidox (SF₆, O₂, Clean Air), Bently on oil pumps and SDT for partial discharges in one procedure.
EN version — draft. Ready to publish once kk/en routing (i18n) is implemented across the site.
At a CHP plant, the step-up transformer bay includes the tank and cooling, line and bus breakers (often SF₆ or GIS), bushings and enclosed switchgear rooms. Failure of any element removes the transformer from service — with the same block derating impact as auxiliary pump trips.
Monitoring matrix:
| Component | Method | KEG TRK |
|---|---|---|
| Internal faults | DGA | Lab / online DGA |
| Oil pumps, fans | Vibration trend | 3500/42M |
| Bushings | Partial discharge | SDT340 |
| SF₆ breakers | Gas quality | Rapidox 6100 |
| Clean Air cells | O₂, humidity | Clean Air Pumpback |
| Enclosed GIS room | SF₆, O₂ | Fixed Detection |
Rollout: baseline (DGA, gas samples, O₂, vibration spectra, ultrasound) → continuous vs periodic layers → dispatcher integration via DCS and System 1.
See also DGA companions and cooling vibration. Scope: power generation; not oil & gas.
